After you order, a link to the download site will automatically be sent to you by e-mail from firstname.lastname@example.org with the link to the download files. Since the sound files are in MP3 format, the files are pretty small, just 154 MB. The course is divided into sections for ease of download. Just load the six disks into iTunes. There are more than 120 segments and they are sequenced by iTunes to make it all easy and fun. Just follow the directions on the page and you will be running in not time. If you wish, Windows media will also handle these audio segments.
